Why is column showing different calculation than a measure?

[mikep7521]

I created 4 Total Columns as you can see in the pictures. The first three are measures and are caluclated using the formula shown in the formula bar:

Total Purchase Amount BK = CALCULATE(SUM(Purchase Amount), FILTER(Asset Class ="Bankruptcy"))

Then I created a cloumn with the following formula:

Total Purchase Amount = SUM(Purchase Amount)

As you can see I'm recieving a different total in the 'Total Purchase Amount' column than I am for the measure. The Total Purchase Amount is segmented by the asset class so why am I recieving two different values as highlighted in picture.

I just made that change by using the Calculate function and the vlues in the Total Purchase Amount column did not change.

I'm confused, can you elaborate how to make asset class segment a row as well as a column?
